Parker has now admitted to Access Hollywood that she had very little time to prepare for the movie.

"It was difficult because, obviously, the circumstances are not ideal," the actress said. "I obviously conveyed that to the filmmakers [and] that I was aware and I was sorry for the reasons that they had to reach out to me."

Parker continued: "Also, of course, the somewhat daunting task of playing somebody with very little time [to prepare for] who was obviously such an important person in the women's movement, but also played such a pivotal role in Linda's life."
